Waves reflect off the surfaces of the model and from sides of the tank. This can be a major limitation on towing tanks where the productively of the whole facility is determined by the settling time after a run has been completed. All tanks have resonant frequencies and often these lie within the working frequencies that are generated in the tank. A good beach will absorb much of the energy after is has passed the model but has little effect on cross-waves or models reflected from the model. Wave makers incorporate proven software techniques for wave generator control and can include software links to towing carriages to optimise test duration. Wave Technology is a rapidly advancing science new or modified products are continually being developed to meet unique experimental needs, including those associated with the offshore industrys deep-sea exploration research programmes. Active absorbing wavemakers dramatically increase the performance of a tank by prolonging the time that an experiment can run without the build up of spurious waves and also by decreasing the settling time between runs.

In Gas Absorption Trainer With DCS Control trainer, an air CO2 mixture emulates the raw gas stream and CO2, the acid gas. The amine is regenerated and recycled through the process. The Gas Absorption Trainer With DCS Control is equipped with industry typical process measurement and control devices, providing a realistic training environment in which the students are exposed to many available technologies. The separation of gas mixtures and recovery of the components usually involves a regenerable absorbent. In the natural gas processing industry sulfur compounds and CO2 are removed by absorption by an aqueous amine solution. The trainer is controlled from a distributed control system.

Absorption is used to remove one or more gaseous components from a gas flow using a solvent. The flow rates of the gas components are displayed. A compressor delivers the gas mixture into the lower section of the absorption column. First of all, a CO2 and air gas mixture is produced. Water is used as the solvent. The CO2 is absorbed by the downward flowing water. As the pressure is reduced and the temperature is increased, the solubility of the CO2 falls. A heater heats the water. A water jet pump generates the vacuum in the desorption column and causes the CO2 gas to be emitted from the water. To separate the absorbed CO2, the charged water is then fed from the lower section of the absorption column into a desorption column. It is possible to adjust the mixing ratio using valves. A pump then delivers the regenerated solvent back into the absorption column. The water temperature can be controlled. Flow rate, temperature and pressure are continuously measured. In the column, part of the CO2 is separated in the counterflow with the solvent.

The column is supplied filled with glass Rasching rings 9x9 mm, and also supplied with polypropylene Pall rings, for the replacement of the glass Rasching rings in order to be able to study the effect of the filler on the efficiency of the absorption and desorption process. The main element of the Absorption Desorption trainer is a column of 1400 mm. height and 80 mm in diameter made in glass. The plant has pressure taps at the bottom and at the top of the column and two intermediate taps, through quick couplings connected to a water column differential manometer that allows determining the pressure drop within the column and the effects of the speeds of the liquid and of the gas on the pressure drop within the column. In both cases, the column filling maximizes the gas liquid contact surface, so that it produces the maximum possible absorption or desorption.
The Absorption Desorption plant also has three intermediate samplers for sampling both the liquid phase and the gas phase and 4 temperature probes with digital display. In a flow meter positioned on the liquid inlet line can be displayed the liquid inflow. This flow meter is made of borosilicate glass and stainless steel with stainless steel float. The liquid is introduced through the top of the column through liquid diffuser, which permits the dispersion of the liquid and thus a better distribution of the fluid within the column. The liquid phase is stored in a tank of about 30 liters of capacity made of polyethylene. Water or absorption liquid is led into the reaction column through a metering pump, which allows setting the incoming water flow to the column.

The Absorption Refrigeration Cycle Study Unit is an extremely easy-to use and functional unit able to permit the study of an absorption refrigerating cycle. The cycle peculiarityis to generate low temperature using an heat source. The heat can be produced or by an electric source or by a gas burner.The cooling fluid is ammonia (NH3), housed in a sealed circuit. Afront panel with mimic diagram and instrumentation allows to keep the most significant thermodynamic quantities undercontrol, so facilitating the students understanding and the teachers task. The unit is supplied with the electric resistance heater, but it is possible, on demand, to have the gas burner. A refrigerating room allow the cooling effect visualization. The main characteristic of the Absorption Refrigeration Cycle Study Unit is to enable the student to observe the absorption refrigerating cycle.

Absorption refrigeration systems operate using thermal energy. This basic principle is demonstrated in the experimental unit with the example of an ammonia-water solution with the ammonia acting as refrigerant. They use the principle of liquids evaporating already at low temperatures when pressure is reduced. In the evaporator the liquid ammonia evaporates and withdraws heat from the environment. To keep the evaporation pressure low, the ammonia steam in the absorber is absorbed by the water. For this purpose, the high concentration ammonia solution is heated in a generator until the ammonia evaporates again. In the final step, the ammonia steam is cooled in the condenser to the base level, condenses and is returned to the evaporator. The low concentration ammonia solution flows back to the absorber. To maintain the pressure differences in the system, hydrogen is used as an auxiliary gas. In the next step, ammonia is permanently removed from the high concentration ammonia solution to prevent the absorption process from being halted.
